powerpc/fsl: Added binding for Freescale CoreNet coherency fabric (CCF)
The CoreNet coherency fabric is a fabric-oriented, conectivity
infrastructure that enables the implementation of coherent, multicore
systems. The CCF acts as a central interconnect for cores,
platform-level caches, memory subsystem, peripheral devices and I/O host
bridges in the system.

+ The Coherency Subdomain ID Port Mapping Registers and
+ Snoop ID Port Mapping registers, which are part of the
+ CoreNet Coherency fabric (CCF), provide a CoreNet
+ Coherency Subdomain ID/CoreNet Snoop ID to pamu mapping
+ functions. Certain bits from these registers should be
+ set if PAMUs should be snooped. This property defines
+ a bitmask which selects the bits that should be set if
+ PAMUs should be snooped.
